Huawei display went into negative coloured

[Android Central Question]

Hello!
I have a Huawei p8 light and somehow my display went from normal coloured into negative... I have this 360 security app on my phone and there was a button to switch normal colour into reversed but now I am not able to find it and return to normal

Does somebody know how to get it back to normal?

Try Settings, Accessibility, Invert Screen Colours.

Try this:
Go to settings, about phone, accessibility, scroll to "color inversion (experimental)" and turn off by disabling that setting.
